摘要： A burst-mode optical transmitter (405) for receiving reverse electrical signals and for providing a reverse optical signal in a communications network. The optical transmitter includes a carrier-detect circuit (510) for detecting the presence of reverse electrical signals and a laser (535) for converting the reverse electrical signals into reverse optical signals for further transmission. The carrier-detect circuit (510) controls a switch (515), whereby when the carrier-detect circuit (510) detects the presence of reverse electrical signals, the carrier-detect circuit (510) closes the switch (515) activating the laser (535). When a reverse electrical signal is present, the carrier-detect circuit (510) opens the switch (515), deactivating the laser (535). In this manner, the burst-mode optical transmitter (405) only transmits reverse optical signals when reverse electrical signals are present. The reverse optical signals from a plurality of optical transmitters (405) can then be combined and transmitted further upstream via a single fiber path.

摘要： A solution for detecting and recovering from a failure in a protected single-fiber passive optical network. A detector is used to detect the degradation in power level of optical signals. Furthermore, the invention discloses a variable symmetric split ratio approach to improve the number of splits (e.g. the number of ONUs). A single-fiber passive optical network is disclosed that uses a plurality of passive nodes connected in the optical fiber between the interfaces, wherein in the passive nodes 2-by-2 splitters/combiners are used to couple optical power from and into the optical fiber at a predetermined split ratio.

摘要： Data transmission apparatus includes optical transmitters (14a, 14b) coupled to an optical link (10). A FEC coder (40) is coupled to the input of transmitter (14b'). A first signal (12a) having a first rate is provided to the first transmitter, and a second signal (12b) having a higher information rate than the first signal, while simultaneously enabling the respective output power levels of the amplifiers (18a, 18b). The transmission apparatus achieves higher transmission capacity while retaining compatibility with pre-existing fiber spans and amplifier nodes. An optical transmission system incorporates a transmitter (70) and a receiver (72) having certain transmission characteristics, such as output power level, decision threshold level, etc., that are adjustable in response to BER. A BER estimator (74) is provided at the receiving end of the link. The estimator estimates the BER of the received signal, and provides BER to the receiver, and/or transmitter, and/or optical link, based on the estimated BER, to optimize performance.

摘要： An electronic circuit provides a substantially linear output from a nonlinear transmission device such as a laser. The input signal (22) to the nonlinear device (20) is applied to an in-line electrical path coupled to the nonlinear device. In the in-line predistorter of the present invention, the desired real and imaginary distortion terms may be synthesized by summing the distortion contributions from several different distorter elements. In the simplest case, one distorter produces a constant real distortion (16), another produces distortion proportional to frequency, f, and so on. However, it is not essential to have the simplest set of distorters. Distorters with more complex distortion characteristics can be used so long as they provide an independent set. A number of circuits are disclosed that can be combined to provide the building blocks of an in-line circuit.

摘要： An optical chromatic dispersion compensator (60) betters optical communication system performance. The dispersion compensator (60) includes a collimating means (61) that receives a spatially diverging beam of light from an end of an optical fiber (30). The collimating means (61) converts the spatially diverging beam into a mainly collimated beam that is emitted therefrom. An optical phaser (62) receives the mainly collimated beam from the collimating means (61) through an entrance window (63), and angularly disperses the beam in a banded pattern that is emitted from the optical phaser (61). A light-returning means (66) receives the angularly dispersed light and reflects it back through the optical phaser (62) to exit the optical phaser near the entrance window (63) thereof.

摘要： Methods and apparatus are disclosed that apply a predetermined complex-valued spectral transfer function to an input optical field to produce an output field that propagates in an output direction. Methods for making such apparatus are also disclosed. Segmented gratings (1915, 1916, 19a15, 19a16) fabricated according to one example comprise a series of spatially distinct subgratings arrayed end to end. Each subgrating possesses a periodic array of diffraction structures, such as lines or other elements. The transfer functions of such segmented gratings are determined by controlling (a) the spatial periodicity or frequency of each subgrating, (b) the amplitude of each subgrating, (c) the spacing between the last diffraction structure (or line) on each subgrating and the first diffraction structure (or line) of the successive subgrating, and (d) the optical path length and transparency through each subgrating, or each subgrating plus additional material layers utilized to control optical path length and transparency. Communication systems using such segmented gratings are also provided.

摘要： An exemplary composite optical fiber transmission line (200) and method are provided that result in significant advantages. The composite optical fiber transmission line (200) includes a standard single-mode fiber (202), such as an SMF-28 fiber, a dispersion shifted fiber (204), such as an NZDSF fiber, and a dispersion compensating fiber (206). The single-mode fiber (202) receives an input optical signal at a first end and generates a single-mode optical signal at a second end. The dispersion shifted fiber (204) receives the single-mode optical signal at a first end and generates an output optical signal at a second end. The dispersion compensating fiber (206) receives the output optical signal and generates a chromatic dispersion compensated signal that, preferably, is at some desired chromatic dispersion level. In one example, the residual chromatic dispersion of the composite optical fiber transmission line is zero or near zero, and the residual chromatic dispersion slope of the composite optical fiber transmission line (200) is zero or near zero.
